SNOW-REMOVING MACHINE.

Application .filed November The invention relates to certain new and useful improvements in mechanisms for removing snow from streets and highways, with the aid of a conventional form'of motor truck, and it is one object of the invention to provide a pair of bracket plates which may be bolted or otherwise secured to opposite sides of the cab, said plates having portions projecting above said cab, said bracket plates serving to support the upper ends of snow elevating means and also acting as a part of supporting means for a conveyor which carries the snow from the upper end of said elevating means.

Another object of the invention is to provide a motor, separate from the truck motor, for driving the snow elevating means and the conveyor, said motor being mounted in the truck body and protected by a cover late provided for said body.

A f i irther object of the invention is to provide snow-removing mechanism which, while being rather simple and inexpensive, Will be efficient, reliable and generally desirable.

WVith the foregoing in view, the invention resides in the novel subjectmatter hereinafter described and claimed, the description .eing supplemented by the accompanying drawings. 1

Fig. 1' is a side elevation partly broken away and in section showing one formof the invention, operatively mountedzupon a conventional form of motor truck.

Fig. 2 is atop plan view of the parts shown in Fig. 1. I

Fig. 3 is a central longitudinal section, partly in elevation. I

Fig. 4 is a detail transverse section on line 4-4 of Fig. 1.

Fig. 5 is a side elevation showing a different form of construction, in which the snow conveyor extends transversely of the truck instead of longitudinally thereof as in the figures previously described.

' Fig. 6 is an enlarged detaillongitudinal section cut through the upper end of the snow elevating means, the transverse snow conveyor and associated parts.

Fig. 7 is a transverse section on the correspondingly numbered line of Figs. 5 and 6.

Fig. 8 is a top plan view of the parts shown more particularly in Fig. 6.

a guard plate which is detachably connected therewith. i

A motor truck T is Shown having the usual body B and drivers cab C. Inadvance of the truck and connected with it in any desired manner, is a snow scoop S having adjustable scraper plates P and a snow beater B at its front end. Rising from the scoop Sis an elevator E. The parts S, P, B and E are of the same general construction shown in my U. 8. Patent No. 1,506,265 of August 26, 1924 and hence they will notbe described in detail.

Secured by bolts or the like 10to opposite sides of the cab C and projecting upwardly from this cab, are two bracket plates 11 which are disposed in parallel longitudinal planes, the upper front portions of said plates having appropriate bearings 12 for the upper shaft E of the elevator E, while the rear upper portions of these plates are provided with upward projections 13 having their upper ends turned inwardly and down wardly to provide vertical guide members 14 relation with the jections 13. r

A conveyor 15 is'disposed longitudinally overthe truck body B and is provided with a frame 16 whose front end is received between the bracket plates 11 and is pivoted to thesevbracket plates by a shaft 17, which is one of the shafts around which theconveyer belt 'or the like .15, passes. The side members of this frame 16 are slidably received between the .major portions of the projections .13 and the guide members 14 thereof, as most clearly shown in Fig. 4. The pivota-l mounting of the frame 16 permit-s vertical swinging of the conveyor 15 to some extent as occasion may demand and the parts 1314, serve to guide said frame in its vertical movement and hold it against possible lateral canting which would have major portions of the proa tendency to exert undue strain and friction upon the shaft 17. a

A cover plate 18 is provided for the body B, and this plate may well have side flanges 18 detachably bolted at 18". to the sides of Said body. By means of this .cover plate, a motor 20 which is mounted in the body B, is protected to a large extent. The shaft 21 of this motor projects laterally through one side of the body B and is provided with a sprocket wheel 22 which may be connected which, are. disposed in spaced parallel.

with it' or disconnected from it, by means of an appropriate clutch 23, an operating lever for this clutch being indicated at 24. A chain 25 passes around the sprocket wheel 22 and around another sprocket 26011 a transverse shaft 27 which passes through the lower portion of the cab C.

By means of appropriate sprockets and chains 28, the shaft 2'? drives the shaft B of the beater B. Shaft 27 also drives another transverse shaft 29 through the instrumentality of gearing 30 and 31, and by means of a chain 32 and appropriate sprockets,*shaft 29 drives the upper shaft E of the elevator E. This shaft E is connected by suitable sprockets and a chain 33, with the shaft 17 of the conveyor 15.

It will'be seen from the foregoing, that the attachment may be quickly and easily connected with a motor truck and that when snow is to be removed from a street or the like, the-scoop S and elevator E will gather and elevate the snow respectively, and said elevator will discharge it into the conveyor 15, by means of which it may be conducted to any desired receptacle, such as a trailer (not shown) hooked to the rear end of the truck T. As the motor 20 drives all operating parts, undue strain is taken from the ordinary truck motor and the only work left for the latter to perform, is that of advancing the truck and its snow removing mechanism.

In the form of construction shown in Figs. 5 to 9, a number of the parts are identical with those so far described, with the possible exception of proportions, and hence the same reference characters previously used in connection with these parts, have been applied to these views. A transverse conveyor 15 however is used insteadcof a longitudinal conveyor, and this necessitates a number of other changes.

A coverplate18 is provided for the body B said cover late havin an n wardl di- 'rected front end 35 for a purpose to appear. Two bracket plates 11 are secured by bolts or the like 10 to opposite sides of the cab C, but these plates are of L-shape, the bases of said plates being secured to the cab, while their vertical portions project upwardly from the front end of the latter. These upwardly projecting bracket plate portions carry the shaft E of the elevator E. The transverse conveyor l5 over the base portions of the bracket plates 11 and includes an appropriate frame 16,

the front side member 16 of said frame,

being provided with laterally spaced, forwardly projecting cheeks 36 which are disposed at the inner sides of the plates 11 and are formed with openings through which a transverse shaft 37 passes, said shaft being supported by said plates. The rear side member of the frame 16 is provided plate 18 is disposed with an arched seat 38 which receives the upturned front end 35 of the body cover This seat may well be formed by bending a metal plate in a manner most clearlyshown in Figs. 6 .and 8.

An inclined guard plate 39 is disposed between the vertical portions of the plates 11 under the upper end of the elevator E,

'said plate preferably having a downwardly projecting flange portion 4E0 forming a 1611- 7 in portion of the frame side 16 between the cheeks 36. The ends of this guard plate are provided with hooks 41 which hook over the portions of theside member 16, at the outer sides of the cheeks 36; Theguard plate 39 is thus efiectively supported in operative position and it prevents the fallingfof snow onto the front end of the cab r00 p The belt or the like 15 of the conveyor 15 is of coursetrained around appropriate shafts 17 One of these shafts is driven by bevel gearing 4:2, fromthe transverse shafts 37, and the latter is driven by a chain and suitable sprockets, from the transverse shaft 29, the chain being denoted at 43. Additional sprockets and a chain 44 are employed to drive the elevator shaft E from the shaft 37.

The form of construction just described, permits of quick and easy attachment of the snow removing mechanism to a truck and detachment therefrom with equal facility,'and it will be seen'that the transverse conveyor 15 will deliver the elevated snow laterally of thetruek instead of behind the same. 7

Excellent results may be obtained from the general construction shown and described and such construction is therefore preferably followed. However, within the scope 10 of the invention as claimed, variations may of course be made. 7 V
